    Bar code reader or some kind of remote receiver.?

  2. Buzz says:

    An amateur radio amplifier would be my guess based on the MC1590G and the power transistors.

  3. Adrian says:

    I think these are custom HP part numbers on the ICs.

  4. Avi says:

    Near the upper left we have date codes of 8040 and 8114, and near the right 81xx, so I am placing it at the early 80s. Definitely not 2003ish.

    Looks vaguely like a TV pre-amplifier I pulled apart, much to my folks annoyance!

  6. Dmo says:

    This looks like a laser diode driver. However, the vintage of other components suggests otherwise.

  7. Brian says:

    My guess that it’s an HP 10780A Laser Receiver, part of an older HP Laser transducer system.

    My first thought was that it looked similar to some of the older HP O-E converters I’d used for fiber optics stuff, but the MC1590 amplifier B/W was too low for that.

    That led me to look in the 1985 HP catalog at optical sensor stuff, leading to the 5501A Laser Transducer System and its’ receiver.

      It looks like you are almost certainly correct.

      Page 7-3 of your linked PDF contains both a B&W photo of the ware in question as well as the full schematic.

      Nice job! :-)

  9. Brian says:

    There’s an HP Journal article describing the 5501A system, including theory of operation of the 10780A receiver, here:

    Looking further at the PCB layout, there are some minor layout differences between the “A” service manual link I provided and the NTW picture, which could be either production changes or possibly a later version of the module- it looks like the 10780C and 10780F are still in production at Keysight today.

      Sam’s Laser FAQ: “Zygo 7080 looks similar to the HP/Agilent optical receivers but has a 7 pin LEMO connector instead of the funny 4 pin BNC”, Bunnies one has 4 pin connector

    I think it’s part of a tv or remote. I’m quite intrigued with the green bulb in the middle.
